ACSF3 Antibody – Rabbit Polyclonal

This gene encodes a member of the acyl-CoA synthetase family of enzymes that activate fatty acids by catalyzing the formation of a thioester linkage between fatty acids and coenzyme A. The encoded protein is localized to mitochondria, has high specificity for malonate and methylmalonate and possesses malonyl-CoA synthetase activity. Mutations in this gene are a cause of combined malonic and methylmalonic aciduria. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Sep 2013]

Function: Catalyzes the initial reaction in intramitochondrial fatty acid synthesis, by activating malonate and methylmalonate, but not acetate, into their respective CoA thioester. May have some preference toward very-long-chain substrates. Ref.6 Ref.8

Subcellular location: Mitochondrion Ref.8.

Involvement in disease: Combined malonic and methylmalonic aciduria (CMAMMA) [MIM:614265]: A metabolic disease characterized by malonic and methylmalonic aciduria, with urinary excretion of much larger amounts of methylmalonic acid than malonic acid, in the presence of normal malonyl-CoA decarboxylase activity. Clinical features include coma, ketoacidosis, hypoglycemia, failure to thrive, microcephaly, dystonia, axial hypotonia and/or developmental delay, and neurologic manifestations including seizures, psychiatric disease and/or cognitive decline.Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.8

Sequence similarities: Belongs to the ATP-dependent AMP-binding enzyme family.

Sequence caution: The sequence AAH72391.1 differs from that shown. Reason: Aberrant splicing.
